Intel and Advanced Micro Devices swapped roles in a third quarter that wasn't as bad for shipments as some had initially feared, according to new data from Mercury Research. AMD had been making strides in the server market for several quarters, while Intel dominated the notebook market. But momentum swung the other way in the third quarter, with Intel regaining market share in server processors while AMD's notebook processor shipments surged, said Dean McCarron, an analyst with Mercury Research.
